Now that he's recovered from his ordeal, the monster is ready to go back to his normal self. But first, he wants to thank the monster for giving him the holy pill. The holy pill is a powerful elixir that can speed up a cultivator's progress in the golden-core realm and help him ascend to the "basal soul realm" . It's the same elixir that the master of the dream palace used to keep her cultivation safe. The monster is so grateful that he gives it to the monster, even though it's not a magical substance.
